Trumble claimed that her work went beyond looking after Beatrice, Mills' daughter with McCartney. She said Mills required her to blow-dry her hair, work unreasonable hours and spray-tan her naked body.

At the time, Mills' publicist, Joe Dolce, told ABCNews.com, "Heather is devastated. ... For years she has treated Sara as a member of the family."

"Heather's given me the chance to work, where no one else would take me because I have a baby," she says in the video. "She's given me this chance so I can bring my daughter to work with me."

Trumble confirmed to British newspaper the Telegraph that the video was shot by "one of Heather's team" shortly after she started work for Mills, but Dolce denied that she made Trumble or any of her employees shoot such videos. He declined to comment on the current status of the case.

Naomi Campbell

Naomi Campbell's runway strut is almost as famous as her fiery temper. In 2000, the supermodel pleaded guilty in a Toronto court to a 1998 assault on Georgina Galanis, a former assistant who accused Campbell of assaulting her with a telephone in a hotel room and threatening to throw her out of a moving car. After paying Galanis an undisclosed sum and agreeing to attend anger management classes, Campbell's record was cleared.

But, apparently, the classes didn't stick.

Three other employees of the supermodel accused her of physically lashing out at them, most notably former housekeeper Ana Scolavino. In March 2006, Campbell was charged with second-degree assault for allegedly assaulting Scolavino with a jewel-encrusted cell phone. She pleaded guilty to a charge of reckless assault in January 2007 and was sentenced to five days community service and more anger management education.

Britney Spears

As if her child custody battle with ex-husband Kevin Federline wasn't tough enough, Britney Spears got burned by her ex-bodyguard in September 2007 when he appeared as a secret witness. Tony Barretto was prepared to testify about "issues of nudity by Ms. Spears, drug use and safety issues involving the children" that he witnessed as her bodyguard before she fired him in May 2007, according to his attorney, Gloria Allred. But instead of testifying, Barretto's written allegations were entered into court as evidence.
